'1 '0 all well rim it may r'oarrern Be. it; known that l. 'luouxs- T1,. l ritiz'en of the t'nited States. Rochester. in the eonnty oi ace. :1 residing at Monroe and *nteil rertain new and useful Improvements in l"astenin' 'DeVices: and l'do here n" deelare the followiug to he a full. elear. and exurt ileseription of the invention. sueh as will eualile flo'others skilled in the art to whieh it appertains'to make and use the same. 7

'lhis intention relates to a fastening de, \iee' foeuse in set-urine an annular mene her against longitudinal movement upon a 1i shaft.

it "at! Tn fastening an annular meiuher surh. l'or -example. as the rare oi a li.-|ll-hearin upon I shaft. it has heretofore heen proposed to employ a del'ormahle sleeve or ring whieh ahuts against the annular memlier and is |)I'IHI L' Into a slot or other reeess "fort-ed or s in the shaft.

'lhe present invention relates to fasten- 1;; derives of this t \pe. and the ohjeet oi leinvention is to produee a fastening-de- \'ir'ewhieh may he produeed simply and im'xpeusi\'el ol' malleahle sheet-n|etal. and -whieh shall luuso formed that it ina he tort-edinto a groove or reeess in a shal't.

and may at the same .time.he more or less upset against the annular memher whit-h is to he fixed upon the shaft. it provision for sneh upsettiu s of the l'asteuing-deriee, a elose fitting together oi the parts n|a he seeured regardless of tllt sligl'ilt' variations in the dimensions of the. parts due to the ordinary methods of nnmutaeture. so that in every easethe annular memher may he fixed rigidly against axial movement upon the shaft.

To the foregoing end I employ. in the present; invention. a faste.nin;rde.viee of annular 'l'orm. eonsist-infi' ot' hendahle or malleahle. metal. this fastening-device comprisine'. integrally, a sleeve or neelcqiortion 'llitll is adapted -to he slipped orer the end or the shaft and then ioreed into a groove or reeess therein. and a flange which extends outwardly l'rom one end of the sleei'o and isadapted to ahut against; the annular memher mounted on the shaft. ihis llange is united origilmlly with the sieeve r a enrre. rather than a sharp angle. so that. in settin; the l'ast(nine-derive in plaee the axial pressure to whi h it is subjected eauses the llange to he upset and spread against the urt'aee oi the annular memher. wherein" the fasteniHg-deYiee yields sulli eien'tl to permit the other extremit} of the sleere to the engaged with the groove or reress in the shaft. while at the same time preserving" a pert'eetlr tight fit and engagement lit-tween the tasteuing-deriee and the annular memher. so as to insure against an) looseliess oi the-parts alter the fastening deriee has heen tixed in plaee. i ln the aeeouumnying drawin s Figures t and 2 are axial sert'ious ot' a tasteningaievie en luuli'lii il' the present: in\'ention. together with a grooved shaft and an annular memher iu t'ulltltttifllt with which the fasteniuJ-dei'iee is used. Fig. 1 showing the. parts in position prior to the operation of lixingr the .t'astenine -device in plaee, and Fig. *3 sho\\'i n; the parts in the positions assumed at'tei that operation. Fig. 3. is an end-eleration oi the t'asteuing-deriee alone. The invention 'is illustrated as emhodiet in a l'asteuing-deriee having a general form similar to that of an eyelet. This deriee' may he eoureuieutly made h v stamping, from soft steel or other malleable sheetmetal. and eomprises a short: sleeve. or neek 5. and an outwardly extending flange ti,-

these parts heing integrally united in a smooth curve. as shown particularly in Fig. 1. q

The illustrated tastening-dm'iee is used in eonneetion with a -shaft, 8 which is pro- \ided. near one end. with an annular groove 0. i pon the shaft is mounted an annular memher' 7 sueh. for example, as the inner raee of an annular hall-hearing. ,This men her is seated. at its left-hand end. against a shoulder 10 on the shaft, and the-fastening device is employed to retain the race 7 against. the shoulder.

The sleeve-portion 5 of the fastening-derice is of sullieient-diameter to slip easily over the shaft. while the entire length of the deviee is somewhat greater. normally, than portion 5. When this tool is moved from right to left with snfi'icient pressure, the parts assume the position shown in Fig. The slee\-'e-portion 5 of the fasteningalerice is moved toward the left until its edge coincident with the shoulder of the slot 9, whereupon the beveled or rounded surface of the die forces the sleeve-pmtion inwi'irdly, thus bending and. compresing it into the slot. The fastening-device accommodates itselt to the first partof this longitudinal compressing-movement through the yielding ot the flange G, which is flattened or upset and also somewhat spread against the surface of the annular member 7, so that in the final condition of the parts the flange flatter and wider, and the neck-portion shorter and of less diameter, than in the original form of the fastening-device.

It will be apparent that the yielding action above described of the tastcnii'ig-device is such as to accommodate the device to the variations in the dimensions of the parts which may occur in the ordinary processes than the space into which it ,is to be compressed.

1 claim:

The comhinatioin with a recessed shaft and a men'iljier mounted there n, of an integral annular fastening-device of malleable metah comprising; a sleeve normally of greater diamcier than the sh al't. and a flange Ilhl'l'l'lilllY CHi'YiIl" outwardl from one end of the sleeve; the other end of the sleeve lJO- lllg con'i 'n'essed into the recess in said shaft, and the flange being upset against said member mounted on the shaft.
